placing custom images in BI Server

ref: https://biapplications.wordpress.com/2017/04/17/oracle-bi12c-placing-custom-images-in-bi-server-and-reference-using-fmap/ 

For Oracle BI 12c custom content such as images or pdf help files needs to be placed in the following directory:

/domains/bi/servers/obips1/tmp/earmanager/analytics/../res/

where /../ is a dynamic folder name such as v-PLM12aFeu7Y.

Within a Report or Dashboard this path may be referenced using the following syntax:

fmap:file_name

fmap:foldername/file_name (if a subfolder “foldername” was created below /res on filesystem)
